Title: Motor Vehicles
Inventor: CAPON PETER COLIN
IPC: F16H61/22
Filed: 1967-01-27
Abstract: 1,163,175. Controlling change-speed gearing. FORD MOTOR CO. Ltd. 27 Jan., 1967, No. 4125/67. Heading F2D. In a motor vehicle transmission including a manual shift five-speed gear-box and a twospeed axle, engagement of a particular gear combined with engagement or selection of the twospeed axle Low ratio blocks a gearshift from said particular gear to another particular gear. The five-speed gear and two-speed axle combine to give the following sequence of overall ratios: (numbers-gear ratios, letters-axle ratios) 1L, 1H, 2L, 2H, 3L, 3H, 4L, 5L, 4H, 5H. To prevent engine overspeeding, downshifts from 4H and 4L to 3L are blocked. A solenoid N1 is energized and de-energized by a switch S1 to pre-select High and Low ratios respectively of the two-speed axle, the selected ratio being established when the clutch pedal is depressed and the gear lever moved. A spring-engaged stop (not shown) in the gear-box preventing engagement of third gear is retracted by energization of a solenoid K. With ratio 4H engaged, switch S1 is on contact H, and a switch S2, closed only when fourth gear is engaged, is closed to energize a relay N2 to open contacts C1, de-energizing solenoid K to prevent third-gear engagement, and closing contacts C2, If switch S1 is moved to L, it completes a holding circuit via the contacts C2 for the relay N2 so that when fourth gear is disengaged and switch S2 is opened, N2 remains energized to prevent establishment of third gear.
Patent GB-855913-A (GB)
Title: Improvements in or relating to the manufacture of silicon
IPC: C01B33/02
Filed: 1957-02-06
Abstract: <PICT:0855913/III/1> <PICT:0855913/III/2> Ultra-pure silicon, which may be used for transistor manufacture, is produced by dissociation of trichlorsilane vapour in part in a first zone at 800-900 DEG C. to remove impurities and in part in a second zone at least 950 DEG C. Crude silicon, which may be produced in an electric furnace, is reacted with dry hydrochloric acid gas, and the trichlorosilane formed is purified.  Dry HCl gas enters, at 6 (Fig. 1), steel tube 1 containing silicon, mixed with at least 5% copper to act as catalyst, supported on grid 2.  The HCl enters very slowly, or may be diluted with H2 or N2.  Resistors, an oil bath, or warm air are used to heat the reactor to 200-250 DEG C., preferably the temperature is maintained at 240 DEG C. with a temperature around the reactor of 220 DEG C. SiHCl3, which may contain 10-20% SiCl4, passes through 7 to a condenser cooled to -20 DEG C. or under pressure.  The condensate is purified by distillation from first stage vessel 10 (Fig. 2), in a heating bath, through column 11, cooling control unit 12, to increase separation efficiency, and condenser 13. The impure part of the resulting condensate collects in receiver 14, but most passes to second stage vessel 15 where it is redistilled into receiver 18.  The two stage distillation apparatus is made of "Pyrex" (Registered Trade Mark) glass.  A non-reactive gas, e.g. A, N2, or, preferably, H2, is passed at 28 into vessel 19, to which the SiHCl3 is transferred from 18, and the mixture of H2 and SiHCl3, containing less than 20% SiHCl3, flows through 26 to quartz tube 20, part 23 of which is heated to 850 DEG C. by resistors 22, while part 24 is heated to 950 DEG C.  Part of the SiHCl3 is decomposed in 23 and retains last impurities, and dense silicon is deposited in 24, while SiCl4 is withdrawn and condensed. When a layer of silicon has been formed, the SiHCl3 content of the gas may be increased to 20%.  On cooling, the tube 20 breaks due to the adherent silicon layer, so surrounding tube 21 is provided through which A or H2 is passed.  The recovered silicon is finally washed successively with hot hydrofluoric acid, distilled water, caustic soda solution, distilled water, hydrofluoric acid, and distilled water, and then dried.  The hydrogen for diluting SiHCl3 is purified by passage through tubes packed with palladium-coated asbestos to remove oxygen, and caustic soda to remove CO2 and moisture.  The gas is finally dried with magnesium perchlorate and then passes through an absorbent cotton filter.

Title: Improvements in or relating to apparatus for counting small particles
IPC: G06M1/10
Filed: 1956-02-10
Abstract: 856,873. Photo-electric particle counting. EVANS ELECTROSELENIUM Ltd., COLLINS, G. C., and CROSLAND-TAYLOR, P. J. April 29, 1957 [Feb. 10, 1956], No. 4232/56. Class 40(3). [Also in Group VI] Apparatus for counting blood cells in a sample of blood comprises a metering device for injecting a measured quantity of blood in distilled water into a stream of liquid whereby the particles are accelerated to form a narrow column surrounded by liquid, and photo-electric means for counting the cells. A beaker 16 containing the sample of blood in distilled water is placed on a lever 23 at position d. Lever 23 is then pressed to position e, closing a micro-switch 25 zeroing a counter (not shown) and closing a push button switch 21 to start the forward motion of a plunger 12. Lever 23 then returns to position d while plunger 12 forces a stream of liquid out of the upper end of a capillary tube 4 into a counting chamber 6 where it is sucked into the lower end of a capillary 5. A light is placed at one side of the chamber and a photo-multiplier at the other (neither shown). Signals from the photomultiplier representing the blood cells passing in single file across the path of the light are fed to an amplifier and pulse selector, a discriminator, a trigger circuit and then to the counter. An optical system (Fig. 2, not shown) shows the particles bright on a dark background by means of a condenser lens and an opaque stop. An electric motor 97 revolves a cam 95 so as to cause the plunger 12 via a lever 92 to make a return stroke after the forward stroke is completed. The liquid is supplied from a source 30 which is maintained at a constant head by overflow from a telescoping upper part 33 which allows adjustment of the pressure head by a rod 34 secured in a selected position by a grub screw 36. The liquid emerges from a pump 26 to pass through a filter 38, conduit 39, flow gauge 40 and conduit 41 into a reservoir 31 where it overflows into an outer container 32 to flow back to the inlet 29 of pump 26. A valve 19 is held open by the lever 23 engaging a rod 24 at position a to start the suction through the tube 5 at the beginning of a counting operation. The capillary tubes 4 and 5 are adjustable laterally by sliding blocks 54, 62. Plunger 12 passes through a washer of polytetrafluoroethylene, the hole in which is made initially by forcing the plunger through it.
